Currently SA would find Build ID from `SHT_NOTE` to load debuginfo file. However it does not work in some case for example, ELF binaries which does not have `.note.gnu.build-id`section. I see this case in vDSO (vdso64.so) in Linux Kernel 7.2.15-300.fc45.x86_64. This file can be handled in `debuginfod-find` - it can identify Build ID, and can download appropriate debuginfo file, but SA cannot identify it.
It might not be a common case, but we can create such ELF binaries with `strip -R .note.gnu.build-id`, and it works. So it is better to support such binaries in SA. SA already supports debuginfo, but test code is not available. So this PR adds it. We need to separate debuginfo from native library and strip it, so I modified related makefiles to do it in force. It works regardless of `--with-native-debug-symbols` configure option. --------- - [x] I confirm that I make this contribution in accordance with the [OpenJDK Interim AI Policy](https://openjdk.org/legal/ai). ------------- Commit messages: - 8396859: SA should refer PT_NOTE to obtain Build ID Changes: https://git.openjdk.org/jdk/pull/33764/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=33764&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8396859 Stats: 263 lines in 6 files changed: 243 ins; 1 del; 19 mod Patch: https://git.openjdk.org/jdk/pull/33764.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/33764/head:pull/33764 PR: https://git.openjdk.org/jdk/pull/33764
